Mac Mini or Macbook

Hi, Im a collage student who is taking the plunge and buying a mac in the summer when i get the money. By then i will already own an iPad 2 so the portability doesn't really bother me. But was looking for a good computer to have for things that aren't that great on the iPad (i.e. essay writing). I don't own any other the things expected to be with a mac mini (keyboard, mouse).

Anybody owned both and have a preference or can recommend either a mac mini or macbook.
